ClimateDepot.com founder Marc Morano has been called "the Matt Drudge of climate denial," the "king of the skeptics," and "a central cell of the climate-denial machine," and he revels in these descriptions. Although he has no scientific expertise, he is adamant that manmade global warming is a "con job" based on "subprime science." Morano gained prominence working for two of the most vocal climate deniers in the U.S.: Sen. James Inhofe (R-OK), who notoriously called climate change "the greatest hoax ever perpetrated on the American people," and Rush Limbaugh, who we named Climate Change Misinformer of the Year in 2011 for his steadfast denial of climate science and wild conspiracy theories about the climate change "hoax."

These days Morano is paid by an industry-funded group to run the climate denial website ClimateDepot.com. At Climate Depot, Morano serves as the de facto research department for the right-wing media's attacks on climate science, and mobilizes his readers to target individual scientists and reporters for telling the public about climate change threats. The site was instrumental in manufacturing the 2009 "Climategate" controversy, which Morano incorrectly claimed exposed "deliberate manipulation of facts and data" by climate scientists. Morano is a darling of the organization most committed to climate denial, the Heartland Institute. He regularly speaks at their conferences and defended their controversial billboard comparing those who accept climate science to "murderers, tyrants, and madmen" including the Unabomber Ted Kaczynski.

Due to his history of smears and lies, Morano's media influence is usually confined to Rush Limbaugh, Fox News, and conspiracy theorist Alex Jones. But in December, CNN invited him to "debate" Bill Nye on climate science, and in doing so elevated his marginal views to the mainstream press for the first time all year. For all this, Marc Morano has earned the distinction of 2012 Climate Change Misinformer of the Year.
